MACHINE FOR ROLLING SOLES.

Application led October 24, 1927.

This invention relates to a machine for rolling and pressing solesapplied to foot wear. Shoe soles are now cemented onto the shoe upper inmany instances instead of nailing or pegging, and when the sole is soapplied it is desirable that the sole be firmly pressed and rolled outso that the cement will be of equal thickness therebeneath, forming agood strong bond between the shoe sole and the shoe upper.

An object of the invention is to provide a machine for rolling andpressing shoe soles, which is easily and quickly operated, and whichwill exert the desired amount of pressure on the shoe sole to accomplishthe purposes above mentioned.

Another object of the invention is to provide a machine which is soconstructed that the work can be easily and quickly applied to themachine or removed therefrom.

A further object of the invention is to provide .a machine which is ofcheap, simple and durable construction, and which will effectively pressand roll soles applied to foot wear.

Another object of the invention is to provide a machine having a. rolleradapted to be passed over the bottom of a slice sole to press it, andwhich is so constructed that the roller will eXert an equal pressure atdifferent points over the shoe sole regardless of the curvature of thesole.

With the foregoing and other objects in view which will be made manifestin the following detailed description and specifically pointed out inthe appended claims, reference is had to the accompanying drawings foran illustrative embodiment of the invention, wherein:

Figure 1 is a view in side elevation of the improved machine, partsbeing broken away and shown in section.

Fig. 2 is atop plan view of the machine, parts being broken away andshown in section.

Fig. 3 is a vertical section taken substantially upon the line 3-3 uponFigure 1.

Referring to the accompanying drawings wherein similar referencecharacters designate similar parts throughout, the improved machineconsists of frame having a hase Serial No. 228,238.

which may he made up of two angle irons 10 and 11 connected by crossbars 12, 13 and 14. Adjacent one end of the base there are secured twostationary uprights 15 and 16. On the opposite end of the base a pair ofuprights 17 and 18 extend upwardly and have secured thereto channels 19and 20. If desired, the uprights 17 and 18 may be formed by merelybending' the ends of these channels downwardly. The two channels 19 and2O have their flanges or open sides extending toward each other and formtracks on the frame. Their rear ends are connected by a cross bar 21which has a latch har 22 secured thereto adapted to be engaged by springlatches 23. The lower ends of the uprights 17 and 18 are pivoted asindicated at 24 so that the forward uprights and the channels may beswung forwardly or they may be locked in the position shown in Figure 1by the spring latches 23. A carriage is provided which is in the form ofa U- shaped yoke having parallel arms 25 and 26 which are somewhatcrooked as shown in Figure 1, and which have their upper ends connectedby a cross bar 27. The arms 25 and 26 carry pintles 28 intermediatetheir ends, on which rollers 29 are rotatably mounted. These rollers litand roll within the grooves provided by the opposed channels 19 and 20.A roller yoke having parallel arms 30 and 31 connected by a cross bar32, is carried by the carriage and the forward ends of the parallel arms30 and 31 are pivotally connected to the arms 25 and 26 as indicated at33. On the cross bar 32 there is pivoted an upstanding holt 34 which eX-tends upwardly through. a sleeve 35 and through the cross bar 27 havinga wing nut 38 threaded onto its upper end. A coil spring 39 is disposedabout the bolt and is compressed between the cross bar 32 and the sleeve35. A cross bar 4() connects the arms 25 and 26, and has secured theretoa rack 41 which rests within a notch formed in the center of a cross bar42 connecting the two uprights 17 and 18. A short distance above thecross bar 42 there is a shaft 43 adapted to be rotated by means of acrank 44 in bearings provided on the` upd rights. This shaft has a gearft keyed thereto which meshes with the rack 41. From the above describedconstruction it The two cross bars 13 and 14 serve to support a last 46,which last constitutes a workholder and is preferably replaceable or atleast has a replaceable head so that it may accommodate work of varioussizes. A brace member 47 is pivoted to one of the angle irons formingthe base, and when the trame is in its forwardly extending position,this brace is adapted to enter a notch 48 in the upright 17 so as tosupport the frame in its elevated or forwardly swung position. A rollerR is rotatably mounted on-an axle 49 which connects the two arms 30 and81 of the roller yoke.

rbe moved back and forth by means of the gear 45, causing the carriageto move back and torth with its rollers 29 rolling within the channels19 and 20. As clearly shown upon Figure 1, the channels 19 and 21 arecurved so that they are substantially parallel to the top surface et thelast 46. The bolt 34 limits the downward movement o1'2 the roller yokeagainst the action et the coil spring 39, and by virtue oiE the tactthat the track provided by the channels is curved, the roller B will becaused to move through a curved path parallel to the top of the last.rlhe spring 39 urges the roller yoke and roller toward the last andcauses the roller to exert a continual pressure on the shoe sole, whichpressure will be substantially even all over the sole by virtue of thelact that the carriage moves on a track parallel to the last. Byreciprocating the rack 41 back and forth several times, the roller Rwill be caused to press out the shoe sole and to squeeze out surpluscement. It also presses the shoe sole against the shoe upper so that afirm, strong, adhesive bond will be established therebetween by thecement. As soon as the roller R has been moved back and torth over theshoe sole, the desired number ot' times so that ythe sole will beiirnily fastened by the cement, the latches 23 can be caused todisengage the latching bar 22 and the traine can beswung torwardly aboutits pivot 24. It can be held in this position by causing t-he brace 47to enter the notch 48 while new work is being substituted for thatalready on the machine. The pressure exerted by the roller R againstvthe shoe sole can be varied by tightening or loosening the wing nut 38so as to raise or lower the position of the roller on the *carriage.

will be appreciated that a novel machimx is provided which willelliciently, etlectively and quickly cause a shoe sole to be iirmlyadhered to a shoe upper.

Various changes in the details ot construction may be made withoutdeparting from the spirit or scope of' the invention as detined by theappended claims.
